For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] At present, automobile lamps are increasingly tending to be integrated, multifunctional, and occupy a small space. Traditional automobile rear lights include brake lights, position lights, turn signals, reversing lights, rear fog lights, retro-reflectors, license plate lights, etc. Combination lights include brake lights, position lights, turn signals, and reversing lights. However, to achieve the integration of four lamps on a combination lamp, not only does it take up a large space, but the design is also complicated. If the simple arrangement only realizes the function, the corresponding defects will also be exposed. If the structure is simple, it is impossible to achieve multifunctional combination. Only 2 or 3 lights can be simply combined and the light emission is uneven. Traditional rear combination lamps mostly use halogen bulbs, which occupy a large space and have a higher power than LEDs when working, a high lamp cavity temperature, a low life, and a lamp body that is more prone to aging. The light emission method is single and can only use direct light emission. It is easy to cause uneven light emission on the light-emitting surface, obvious granularity, and the lamp beads are dazzling when observed from behind the car, which can easily cause glare and cause interference to pedestrians and following vehicles.

[0034] Most rear combination lamps using LED lamp beads use direct light emission, and do not perform light uniformity treatment to save costs and space. Although this light emission method is simple and crude and has low cost, it has low space utilization and the internal structure of the lamp can be seen from the rear. The uneven light emission of the LED light source can easily lead to a grainy light-emitting surface and cause a waste of LED light. Stray light can easily cause light pollution at night, and the grainy rear combination lamps are obviously dazzling and cause interference to pedestrians and drivers of the following vehicles.

[0035] As the mainstream light source in the current market, LED lamp beads have the advantages of small size, environmental protection and energy saving, long service life, and little impact from environmental factors, and have been widely used in the manufacture of automotive lamps. However, LED light sources have uneven light output, a single light output method, unsatisfactory light refraction, and the inability to control the light output path, resulting in low light utilization of LED light sources.

[0036] At present, the combination lights using LED lamp beads on the market usually do not do uniform light processing to save costs and space, resulting in uneven light emission of the LED light source and a grainy feeling on the light-emitting surface, resulting in low utilization rate of the LED light source, which is easy to cause interference to pedestrians and drivers of following vehicles. It can improve the uniformity of LED light source emission, reduce the grainy feeling on the light-emitting surface, improve the utilization rate of the light source, and avoid interference to pedestrians and drivers of following vehicles.

After being fixed with screws, the decorative frame 7, the turn signal thick-walled part 4, the brake light thick-walled part 5 and the base 3 can be connected and fixed. The edges of the decorative frame 7 corresponding to the first position light emitting unit 301 and the second position light emitting unit are each provided with an extension rib on the upper and lower sides.

Specifically, the decorative frame 7 can be made of black PC material, and light-blocking walls of different heights and thicknesses are provided between the first position light emitting unit 301 and the turn signal light emitting unit 302, and between the second position light emitting unit and the brake light emitting unit, so that the light emitted by them does not interfere with each other.

[0055] In one possible implementation, a diffusing agent is disposed inside the position lamp's internal light distribution lens 602 to evenly mix the emitted light. The diffusing agent may be a microsphere product produced by polymer polymerization technology through cross-linking, grafting functional groups and other technologies, which can increase the scattering and transmission of light, while shielding the light source and the dazzling light source, and can make the entire resin emit a softer and translucent light.

[0056] In a possible implementation, a black mirror edge 201 and a red mirror edge 202 are provided on both upper and lower sides of the exterior mirror housing 2 , and a white mirror edge 203 corresponding to the reversing light emitting unit 304 is provided in the middle of the exterior mirror housing 2 .

[0057] Specifically, the outer mirror housing 2 can be made of PMMA material, such as polymethyl methacrylate, which has excellent transparency and resistance to climate change. The black edge 201 of the mirror has the effect of shielding the internal structure of the lamp and blocking stray light, avoiding defects such as exposure of the internal structure of the lamp and light leakage at the edge; the white edge 203 of the mirror can be used for the reversing light emitting unit 304 to evenly refract the reversing light source through the white edge 203 of the mirror when the reversing light unit 304 emits light, after the reversing light reflector 303 reflects the converted light source and the reversing light inner mirror 601 evens the light, so as to expand the illumination range of the light and make the road behind the vehicle more evenly illuminated. The red edge 202 of the mirror is a light red transparent effect, which is used for the light distribution of the turn signal light unit 302, the brake light light unit and the position light light unit, and fully and evenly refracts the light emitted by the above light units.

[0058] In a possible embodiment, ventilation caps 8 for heat dissipation are fixedly connected to the upper and lower sides of the lamp housing 1. The ventilation caps 8 can dissipate heat and balance the internal and external air pressure when the rear combination lamp is working. A wiring harness assembly 9 and a wiring harness connector fixing hole are also provided at the lower end of the lamp housing 1, which can facilitate the fixing of the wiring harness and the installation of the docking end wiring harness.

[0059] In summary, the multifunctional rear combination lamp of the present application combines three light-emitting modes, namely, the reversing lamp adopts LED side projection, reflector reflection, inner light distribution mirror uniform light, and outer light distribution mirror light emission to achieve the uniform light-emitting effect of the reversing lamp; the position lamp adopts LED direct emission, inner light distribution mirror uniform light, and outer light distribution mirror light emission to achieve the uniform light-emitting effect; the brake lamp and turn signal lamp adopt LED direct emission, thick-walled part focusing light guide scattering, and outer light distribution mirror light emission to achieve the uniform light-emitting effect, which combines the four functions of reversing lamp (white), rear position lamp (red), turn signal lamp (amber), and brake lamp (red), and the four functions can emit light evenly, and can form a variety of combined light-emitting forms.
